Abstract: 1,177,569. Sodium tripolyphosphate. CENTRAL GLASS CO. Ltd. 22 Sept., 1967 [13 March, 1967], No. 43304/67. Heading C1A. Sodium tripolyphosphate (Form II) is prepared by converting wet process phosphoric acid to substantially pure microcosmic salt, NH4NaHPO4, which is mixed with one or more basic sodium compounds to give a mole ratio Na2O : P2O5 of 5 : 3, heating the mixture to expel ammonia, heat-treating the mixture in a spraying tower at at least 180‹ C., and then calcining it. Impure wet-process phosphoric acid of about 30% P2O5 concentration is neutralized with liquid or gaseous ammonia to a pH of 3À2 to 6, and the greater part of the impurities in the phosphoric acid, such as Fe, Al, Si, F, are deposited as precipitates which are separated from the NH4H2PO4 solution, to which is then added a basic sodium compound such as soda-ash or caustic soda in sufficient quantity to produce a mole ratio Na2O : P2O5 of 1 : 1, so that microcosmic salt is formed. The solution is cooled and the crystals of pure microcosmic salt which separate are dissolved, after washing, in a small amount of heated water, and basic sodium compound is added to give a mole ratio Na2O : P2O5 of 5 : 3. The mixture is heated to expel ammonia, which is recycled, together with the mother liquor from the microcosmic salt crystals, to the beginning of the process. The liquid remaining after heating, which contains Na2HPO4 and NaH2PO4 in molar ratio 2 : 1, is sprayed, at temperature 180-280‹ C. down a tower whose air temperature. is at least 180‹ C. to dry and partially dehydrate the mixture, and the production of sodium tripolyphosphate is completed by calcination at 250-450‹ C.
